Ch 7

Question 0

Which trends increase down and left?

Answer 0

AR, reactivity of metals

Question 1

Which trends increase up and right?

Answer 1

EA, IE, EN, reactivity of non metals

Question 2

Z*

Answer 2

= Z-s

Effective nuclear charge

Question 3

Electron attachment enthalpy becomes more negative _____

Answer 3

Up and right

Question 4

Why is EA and DeaH opposite signs?

Answer 4

Higher affinity - more spontaneous rxn when e- join atom - more exothermic - more neg DeaH

Question 5

Valence e- of transition metals

Answer 5

Highest n shell - n-1 d subshell

Question 6

Which she’ll do you remove e- from atoms?

Answer 6

From highest n shell

Question 7

Removing e- from V, which orbital first?

Answer 7

4s

Question 8

Which orbital do you add e- to?

Answer 8

Lowest E available

Question 9

nodes in 3d orbital

Answer 9

2

Question 10

Electron assigned to orbitals in order of increasing energy

Answer 10

Aufbau principle

Question 11

Hunds Rule

Answer 11

e- spread out amongst all equal energy orbitals before pairing up

Question 12

Pauli exclusion principle

Answer 12

No 2 e- can have same 4 quantum #

Question 13

Largest atom in isoelectronic ions

Answer 13

Most negative ion (lowest Z, lower nuclear attraction)

Question 14

F vs F-, which is smaller?

Answer 14

F (less e-e repulsion, same Z*)
